TIMP-3 Plays a Key Regulatory Role in the Cleavage of E-Cadherin and Has an Essential Protective Function in Hepatic IRI.
T. Fujii, S. Duarte, R. Busuttil, A. Coito.
Surgery, David Geffen School of Medicine at UCLA, Los Angeles, CA
Liver ischemia-reperfusion injury (IRI) remains a challenging problem in clinical orthotopic liver transplantation. Tissue inhibitor of metalloproteinases-3 (TIMP-3), an extracellular matrix-associated protein, has been linked…

Macrophage Specific Deletion of RhoA Impedes Macrophage Functions and Abrogates Chronic Rejection of Cardiac Allograft.
Y. Liu, W. Chen, X. Li, R. Ghobrial, M. Kloc.
Surgery, The Houston Methodist, Houston, TX.
Objective. Chronic rejection of transplanted organs remains the main obstacle in the long-term success of organ transplantation. Chronic rejection occurs in 40-45% of recipients at…
